explain_truncate_or_die(3) Library Functions Manual explain_truncate_or_die(3)
NAME
explain_truncate_or_die - truncate a file and report errors
SYNOPSIS
#include <libexplain/truncate.h>
void explain_truncate_or_die(const char *pathname, long long length);
DESCRIPTION
The explain_truncate_or_die function is used to call the truncate(2) system call. On failure an explanation will be printed to stderr,
obtained from explain_truncate(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_truncate_or_die(pathname, length);
pathname
The pathname, exactly as to be passed to the truncate(2) system call.
length The length, exactly as to be passed to the truncate(2) system call.
Returns:
This function only returns on success. On failure, prints an explanation and exits.
